An experimental service composition tool for media-centric networked applications

Abstract

In order to explore diverse type of media-centric service composition in real environments, we have built a service-oriented testbed named as FIRST@PC (Future Internet Research on Sustainable Testbed based on PC). FIRST@PC targets a flexible and cost-effective testing environment where media-centric service compositions are flexibly realized on top of computing/networking resources. In this paper we design and implement an OMX (Open Media eXperiment for service composition) experiment control tool to support media-centric service composition. By following the SOC (service-oriented computing) paradigm, the OMX tool assists experimenters to flexibly integrate computing and networking services. To explore the possibility of media-centric service composition, we also prototype the FIRST@PC testbed consisting of multimedia computing and networking devices. The implemented OMX tool is verified by an HD media service composition scenario run on this prototyped testbed. (C) 2014 Elsevier B.V. All rights reserved.
